Key result
Significant LMCA disease occurs in ~6% of CAD patients, predominantly affecting the distal bifurcation.
Why the study?
The anatomical pattern and site of left main coronary artery stenosis are important for determining management options but are not well characterized in patients undergoing coronary angiography.
Population
1911 patients with significant coronary artery disease undergoing coronary angiography at King George Hospital, Visakhapatnam
Design
Observational angiographic study

Hypothesis-generating for PCI in LMCA stenosis; leaves open need for RCTs versus CABG.

Malladi Srinivasa Rao (2015) conducted an observational in Coronary artery disease with left main coronary artery (LMCA) stenosis (n=1,911). Left main coronary artery (LMCA) stenosis was evaluated on Prevalence and anatomical pattern of LMCA involvement. Significant left main coronary artery stenosis was observed in 6.1% of patients with coronary artery disease, most commonly involving the distal bifurcation (70.3%) and associated with triple vessel disease (78.8%).
